Centrifugal pumps of NC series

  Centrifugal pumps of NC series is intended to pump various liquids:

  • abrasive hydraulic fluids (clay and gravel mortars, mixtures of water and sand, ore, etc.);
  • flushing liquid used in the course of well drilling;
  • household and industrial waste waters;
  • spent flushing liquid (into cyclone plant to clean it of drilled solids;
  • cement mortars.

Advantages of centrifugal pump NC-R1:

  • simple maintenance;
  • light weight;
  • compact size;
  • extreme durability;
  • minimal installation space requirements;
  • all parts are steel casted;
  • stainless steel impeller;
  • increased wearing resistance of pump components;
  • horizontal or vertical layout;
  • versatile, modular design that allows customers to purchase only the parts necessary for repairs;
  • ability to alter rotation direction, which is possible because it is simple to install an impeller suitable for the necessary rotation and volute direction (only the impeller is to be replaced, while all other parts remain the same);
  • exposed impeller.
